✦ Synopsis

In this paper, two-phase horizontal partitioning of distributed databases is addressed. First, primary horizontal fragmentation is carried out on each relation based on the predicate affinity matrix and the bond energy algorithm. This is an application of a vertical partitioning algorithm to the horizontal fragmentation problem. Second, the derived horizontal fragmentation is further performed by considering information related to the global relational database schema and its transactions. A necessary and sufficient condition for the correctness of derived fragmentations is also proved.

This paper considers a distributed database represented by the relational model, and proposes an efficient procedure to reflect the update of the base relation for materialized views defined by the inequality query from the base relation in the element database. Methods to reflect updates of the bas
